Given numbers are 405, 396, 492, 491

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 491 are 491

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 405, 396, 492, 491

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(405, 396) = 17820

GCD(405, 396) = ( 405 x 396 ) / 17820

= 405 / 396

= 405

Step2:

LCM(9, 492) = 1476

GCD(9, 492) = ( 9 x 492 ) / 1476

= 9 / 492

= 9

Step3:

LCM(3, 491) = 1473

GCD(3, 491) = ( 3 x 491 ) / 1473

= 3 / 491

= 3

So, Greatest Common Divisor of 405, 396, 492, 491 is 1
